Description

Intensified high-viscosity fluid mixing device

Technical Field

The utility model relates to an intensify high viscosity fluid mixing arrangement, especially relate to an intensify high viscosity fluid mixing arrangement with feeding distributes function.

Background

The mixing of high viscosity fluids is a common unit operation in industry, and the mixing of high viscosity fluids is encountered in rubber, petroleum, plastics, coatings, inks and synthetic fibers, cosmetics, pharmaceuticals, food, paper and cement industries. With the vigorous development in the fields of life science, electronic packaging, rapid manufacturing and the like, the requirements on the mixing and flow control precision of high-viscosity fluid materials are increasingly raised. Under the urgent demand of continuously improving the safety, cleanness and automation degree of the production process, the mixing process of the high-viscosity fluid urgently needs to develop new technology and equipment with low cost, high-efficiency mixing and accurate metering.

In general, industrially, a fluid having a viscosity of less than 5Pa · s is called a low viscosity fluid, a fluid of 5 to 50Pa · s is a medium viscosity fluid, a fluid of 50 to 500Pa · s is a high viscosity fluid, and a fluid of more than 500Pa · s is an ultrahigh viscosity fluid. The fluid mixing mechanism can be divided into: convective mixing, shear mixing and diffusive mixing, the mixing of which is mainly achieved by shear mixing and convective mixing, due to the small diffusive mixing effect of highly viscous fluids. At present, the high-viscosity fluid mixing apparatus widely used in industry mainly has two types, vertical type and horizontal type. The vertical mixing device can be divided into a vertical single-shaft mixing device and a vertical double-shaft mixing device according to the structure. The diameter of the paddle of the vertical single-shaft mixing device is generally similar to the diameter of the device, and the corresponding stirring paddles are in the forms of ribbon paddles, anchor paddles, frame paddles, Ekato paddles and the like. The mixing equipment is widely applied to the petroleum refining and catalyst production industries due to the simple structure. The vertical double-shaft mixing equipment generally adopts a form of combining a large paddle and a small paddle, the small-diameter paddles rotate at a high speed to ensure the rapid dispersion and mixing of materials, and the large-diameter paddles rotate at a low speed to ensure the macroscopic flow of a near-wall area. The mixing equipment is widely applied to the industries of paint, printing ink and the like. Similar to the vertical type, the horizontal type mixing apparatus is also classified into a single shaft and a double shaft mixing apparatus according to the structure. The horizontal single-shaft mixing equipment has simple structure, and the paddle has the forms of a disc type, a spiral belt type, a double-spiral type, a Z type, an E type and the like, and is widely applied to the industries of rubber, plastics, buildings, food and the like. The horizontal double-shaft mixing equipment has more forms, comprises a double-shaft eccentric disc, an elliptical disc, a T-shaped blade and the like, and is particularly suitable for mixing high-viscosity and ultra-high-viscosity powder systems. The mutual scraping between the stirring members on the double shafts can realize the self-cleaning function during rotation, and is beneficial to the continuity of the reaction of high-viscosity materials.

The vertical mixing equipment is generally operated intermittently, has long mixing time, high energy consumption and low production capacity, and is suitable for mixing small-batch materials. Although the horizontal double-shaft mixing equipment has high mixing efficiency, the stirring power consumption is high, and meanwhile, the requirement on the sealing property is higher, especially under the condition of higher vacuum degree; when the two stirring shafts rotate in the same direction or in opposite directions at a certain rotation speed ratio, interference may occur at high temperature or when the equipment shakes violently. The horizontal single-shaft mixing equipment is simple in structure, and the rotor on the rotating shaft and the stator on the barrel wall are combined to realize rapid mixing and self cleaning of high-viscosity materials. Patent CN203591806U discloses a horizontal reactor suitable for ultra-high viscosity fluid, which realizes the reaction and homogenization of high viscosity material through helical blades on the stirring shaft and return holes on the blades. Patent CN102942688B discloses a single shaftless high viscosity polyester continuous production device, which adopts a film pulling internal part consisting of a plurality of T-shaped movable and static scrapers to realize the reaction and homogenization of materials. Patent CN204051489U discloses a high-efficient blending tank, and it adopts and moves crowded charging tray and quiet retaining ring cooperation and stir the compounding, has improved mixing efficiency and quality to high viscosity material effectively. Patents CN201978687U and CN201969513U disclose a static bar kneader, which achieves sufficient stirring and mixing of materials by kneading of a static bar and a static bar. None of these horizontal uniaxial kneaders takes into account the problem of the distribution of the feed. Patent CN1279120C discloses a process for continuously preparing a high viscosity silicone composition by first mixing and kneading the materials using a synchronously or counter-rotating mixing rotor in a cascade kneading apparatus having at least two kneading chambers and then reacting and degassing the crude mixture in a screw reciprocating kneader. CN203418782U discloses an extrusion kneader with a temperature control device and a liquid injection device, which realizes rapid dispersion and mixing of acid by an axial injection acid adding port and a stirring screw rod, thereby improving the reaction effect. In summary, the stator-rotor type mixer realizes the mixing of the fluid by means of the rotary cutting of the rotor and the flow guiding effect of the stator, and has good tangential mixing effect; but has the defects of low radial flow speed and poor radial mixing effect from a rotating shaft of the mixer to the wall surface, and the uniform mixing can be achieved only by a multi-stage stator-rotor mixing unit. In order to strengthen the mixing of multi-component high-viscosity materials, the material inlets are reasonably arranged to realize the coarse mixing of the materials while the dynamic and static stirring rotors are arranged in pairs to realize the quick shearing and mixing of the materials, and suitable mixing internals are arranged to realize good radial mixing.
